Knowledge retention involves ‘‘embedding knowledge in a repository so that it exhibits some persistence over time” (Argote et al., 2003, p.572). The repository may be an individual or an information system. The individual’s retained knowledge evolves through their observations, experiences and actions (Sanderlands and Stablein, 1987). Gable et al. (1998) observed ‘‘staff poaching” and ‘‘knowledge drain” due to the ES skills-shortage during the latter half of the 1990s, thereby highlighting the importance of organizational knowledge retention strategies for lifecycle-wide ES-success.
